"Hey fellow Linux users, just had a rough day with my mining rig. It was hit by a pretty nasty crash and now I'm trying to debug a rogue process that's still running in the background. Anyone have a clue how to track it down and kill it?"
"Dude, I've been there too, been dealing with a rogue process that just wouldn't quit even after a shutdown. Ended up using 'pkill' in combination with 'ps aux' to track it down and terminate it. Made a note to check my logs more often next time"
"Yooo, I feel you OP. I once had a Linux box that got taken over by a zombie process and it was a nightmare to track down. Did you check your system logs for any clues on what might've caused the crash?"
"Hey OP, just wanted to chime in - have you tried using `kill -9` to force terminate the rogue process? That usually sorts me out when I'm dealing with a stuck process. You might also wanna check out `systemd-coredump` to see if it's logged anything helpful."
